Daneel Olivaw, the robot from Asimov's Caves of Steel/Robots of Dawn set of books.

Forward the Foundation elaborates on her life with Hari, and the conditons of her death and subsequent revelations of Hari Seldon reveal that she as well was a robot, though her origins were never dealt with in the same detail as those of R. Daneel Olivaw.
